Morphology of Leaf Epidermis and Achene in Ficus of Zhejiang under Scanning Electronic Microscope

Morphology of leaf epidermis and achene of 12 species (including varieties)in Ficus of Zhejiang was examined under scanning electronic microscope (SEM). The results show that stomata are found in all abaxial epidermis, but not in adaxial epidermis; that the inner margin of outer stomatal rim is sinuotate, erose or smooth; and that the cuticular membrane of leaf epidermis is with fine striated shallow wave, coarsely striated deep wave or worm-striated. The achene is divided into four types: Ridge-form. Wrinkled-wave. Nipple-form and Shallow wave. All the differences can be used as subsidiary characteristics to distinguish species or varieties from one another and have some systematic significance to the taxonomy of Ficus.
